The rover team has kept Opportunity productive while engineers continue to evaluate the best posture for carrying the robotic arm when the rover resumes driving.

The arm's position can be manipulated for full use of all the tools on the arm despite symptoms that suggest a broken wire in the winding of a shoulder-joint motor of the arm. The choice of a new position for carrying the arm during drives is a precaution against having the arm stuck in a stowed position if that motor becomes unusable in the future.

Opportunity's recent activities have included imaging of Jupiter, observing the atmosphere on every sol, progress on a multi-filter panorama of "Erebus Crater," and long integrations with the Moessbauer spectrometer and alpha particle X-ray spectrometer on targets "Ted" and "Hunt."
